What is ectropion? Ectropion is an abnormality of the eyelids in which the lower eyelid rolls outward or is everted. This causes the lower eyelids to appear droopy. Ectropion exposes the delicate conjunctival tissues that line the inner surface of the eyelids and cover the eyeball, causing drying of the tissues, resulting in conjunctivitis.
Risk factors. Factors that increase your risk of developing ectropion include: Age. The most common cause of ectropion is weakening muscle tissue associated with aging. Previous eye surgeries. People who have had eyelid surgery are at higher risk of developing ectropion later. Previous cancer, burns or trauma.
